iOS OK button missing creating/editing mission name

Hi, On iOS on iPhone, when creating or editing mission name, if you go to another app and come back to map pilot pro, the screen shows the name field and the keyboard, but there is no ok or save button. And hitting return on keyboard doesn’t do it. I experienced this after creating a mission, when I wanted to save it. Had to swap to another app for a second and when I got back, I couldn’t save the mission. I lot it and had to recreate it. Many thanks for your help. Mathieu
